Title: Structures and fabrication methods for planar mosfet devices
Inventor: WANN HSINGEIEN
IPC: H01L21/28
Filed: 1999-08-10
Granted: 2001-02-21
Abstract: Planar MOSFETs with self-aligned contacts and metal-strapped gates and fabrication methods therefore are described that alleviate the need for a big spacer by potentially eliminating the silicide and the deep junction. The parasitic resistance of the MOSFETs is also reduced since metal is incorporated for the gate, and metal contacts on source and drain electrodes are placed as close to the channel as possible. Since a deep junction is not needed, in the fabrication method two implant masks are saved and subsequent thermal activation is avoided. In the fabrication process, protruding isloation structures are formed in a substrate. An additional masking step is used to open up more area for a gate electrode contact. A gate oxide is grown after which a polysilicon layer is deposited, polished, and planarized with respect to the protruding isolation structures. The polysilicon layer is doped with the desired impurity for CMOS processes. Gate level lithography is performed using a photoresist layer and a hard mask material. Ion implantation is then performed to form source and drain junctions and spacer oxide is deposited and reactively ion etched to expose the source and drain and to form spacers. Metal is deposited, polished and planarized with respect to the protruders isolarion structures to form self-aligned contacts. The polysilicon layer is removed by etching. Metal is again and planarized to fill the space where the polysilicon was removed and complete the gate, source and drain electrodes to form the final structure.
